What the researchers found
Collagen peptide group saw a 2.4 kg increase in fat-free mass and a 1.2 kg decrease in fat mass compared to placebo.
Why it matters
This research highlights the potential of collagen peptides as a supplement for improving body composition and muscle strength, particularly in middle-aged men who are untrained.
How the study worked
A randomized controlled trial with 97 participants divided into three groups receiving different supplements during a 12-week resistance training program.
What this study cannot tell us
The study focused only on middle-aged, untrained men, limiting generalizability to other demographics.
